Summary
Comorbidity, not gene polymorphisms in surfactant proteins, was the main risk factor for severe influenza A (H1N1)pdm09 and fatal outcomes in Moscow. This study highlights the significant impact of pre-existing conditions on influenza severity.
Area of Science:
- Genetics and Molecular Biology
- Infectious Diseases
- Respiratory Medicine
Context:
- Influenza A (H1N1)pdm09 poses a significant public health threat, with severity influenced by various factors.
- Genetic variations, particularly in surfactant proteins, are investigated for their potential role in disease susceptibility and progression.
- Understanding these factors is crucial for developing targeted prevention and treatment strategies.
Purpose:
- To evaluate the association between gene polymorphisms of surfactant proteins (SFTPA2 and SFTPB) and the susceptibility and severity of influenza infection.
- To investigate the role of specific SFTPA2 (rs1965708, rs1059046) and SFTPB (rs1130866) polymorphisms in the course of influenza in a Moscow population.
- To identify potential genetic markers influencing influenza outcomes.
Summary:
- Genotyping of 320 influenza patients and 115 healthy controls revealed high prevalence of SFTPA2 and SFTPB genotypes previously linked to severe respiratory conditions.
- No significant association was found between the studied SFTPA2 and SFTPB gene polymorphisms and severe A(H1N1)pdm09 influenza or unfavorable outcomes.
- Comorbidities, including cardiovascular, endocrine, and respiratory diseases, were prevalent in patients with severe influenza and were identified as the dominant risk factor for severe disease and mortality.
Impact:
- This research indicates that comorbidity, rather than the investigated surfactant protein gene polymorphisms, is the primary determinant of severe A(H1N1)pdm09 influenza outcomes in the studied population.
- Findings suggest that clinical management of influenza should prioritize addressing underlying health conditions.
- The study underscores the importance of considering multifactorial influences, including genetic and non-genetic factors, in understanding influenza pathogenesis.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

19.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...
